" Premium “real-time track position” screens are a mere work of fiction (we have a TV, so can check ...)
Ignoring the app freezes and such I'm really surprised by the above comment, especially coming from a reader of a tech website.
Presuming the cars are tracked via GPS the car has to get its position, beam that to trackside receivers (or the teams own receivers), that then gets forwarded to local FoM servers (where its processed for the pit/garage screens) and then passed along to a data centre somewhere in the world. This then has to work its way to your ISP (and given that you could be on the complete opposite side of the world to the datacentre) and then who knows what priority your ISP gives that traffic before its squirted into your device.
THEN realise that the single practice/quali/race TV feed, produced by FoM, is delayed on purpose by FoM before its shared with the various OB trucks (that are used for pre/post race segments and muxing the commentary by individual broadcasters). From the OB trucks its then sent to the the respective broadcasters distribution centres before being sent on to local transmitters or fed back up to satellites before being piped into homes. In the case of syndicated broadcasts an intermediary hop can be introduced; like Australia, I believe, gets its feed from the BBC, which the BBC has to send to the Oz broadcaster before its distributed to homes by whatever means.
And the reader really thought the "real-time" track-position would really match the "live" TV pictures? One only has to look at remote interviews conducted via satellite on News broadcasts to see the kind of delay just one hop introduces.
